Nebulosity around Sh2-101 Nebula in Cygnus

Looking toward the constellation Cygnus, a stunning and complex region of nebulae strewn along the plane of our Milky Way galaxy is revealed in this sky view. The image emphasizes cosmic gas clouds in a wide field centered on the Sharpless 101 Nebula, a faint emission type nebula known also as Tulip Nebula, in the well known Northern Cross asterism. These Cygnus nebulosities are all located about 2,000 light-years away. Along with the Sun, they lie within the Orion spiral arm of our galaxy.

The full-resolution version of this image is about 289 Megapixels and has a resolution of about 1 arc-second per pixel. The area of sky shown here is about 4,8 x 4,6 (for comparison, the full-Moon disc has an average diameter of about 0,5). The color composite has been completed on November 13, 2005.
The full-resolution image

This color composite image is based on data coming from several photographic plates taken between 1989 and 1991 through the Palomar Observatory's 48-inch (1,2-meter) Samuel Oschin Telescope as a part of the second National Geographic Palomar Observatory Sky Survey (POSS II). The photographs were recorded on two type of glass photographic plates - one sensitive to red light and the other to blue - that later were digitized.
